Consider it a convention. Basically, it doesn't make much sense to register many more digits after a digit that is uncertain. Another common convention is to enclose uncertain digits - often the last two digits shown - in parentheses, for example, 6.67384(80)×10−11 for the gravitational constant in SI units.,
